World's Most Expensive Hot Dog Lands in New York

You've heard of ultraluxe burgers made with braised short ribs and foie gras selling for $100 a pop -- in fact, a similar burger made news when it debuted at the Old Homestead Steakhouse in the Boca Raton Resort & Club in 2006. But supped up hot dogs costing nearly as much? Now that's crazy talk.

Well, that's precisely what's going down at Serendipity in New York. The famous ice cream shop already owns the Guinness world records for Most Expensive and Largest Ice Cream Sundaes. But now it's setting its sights on hot dogs.
